So I decided to tear my 3.73LSD apart while my car is in the garage for winter.
I work with a guy who builds Porsche race cars and while I was pulling apart the LSD carrier, he started to recognize some of the parts. It turns out that the LSD unit shares almost all its internal parts with the one Porsche uses, which is made by ZF. And all of those parts are still available.
Here's all the part numbers:
"Disc with external splines" is available in different thicknesses to adjust preload. The stock discs in my diff were 2.0 mm thick and I replaced them with 2.1 mm discs and new friction discs.
I won't be able to test it out for a few months, but I'm expecting at least like-new performance- hopefully slightly more agressive lock-up due to the increased carrier preload.
